This series adds support for the Tegra2x's display peripheral. This supports the LCD display on Seaboard and we use this to enable console output in U- Boot on the LCD.
Applied to tegra/next and pushed to denx.de. ./MAKEALL -s tegra20 is OK, checkpatch is clean. Thanks.
I'll do some testing on my Seaboard while I run a ./MAKEALL -a arm.
The above MAKEALL build (arm) fails on the Lubbock, zipitz2, palmld and
palmtc builds with the following error:
common/libcommon.o: In function `lcd_sync': /common/lcd.c:125: undefined reference to `flush_dcache_range'
These builds use the 'pxa' arm cpu type, and perhaps don't have an
implementation of the dcache routines.
I'll need a fix before I can submit a pull request to Albert for this.
Note that there are a couple of other arm builds (tx25 mx31pdk) that also
fail, but not due to any Tegra or LCD reason - it appears they fail in arm/master, too, so they can be ignored for now.
Ah ok. I will take a look.
OK, I found that pxa doesn't have this function. Some boards define CONFIG_SYS_DCACHE_OFF and some don't.
So I have amended one of the LCD commits to look for that, and resent it.

I have also created a commit to update zipitz2, palmtc and palmld to define CONFIG_SYS_DCACHE_OFF. I hope that is acceptable to the maintainer.

Looks good so far (I've only done a ./MAKEALL -c pxa; I'll repeat the ./MAKEALL -a arm tonight). I'll send up a new tegra/next with a revised V8,11/16 patch tomorrow morning if all goes well.
